X is a non-volatile solute and Y is a volatile solvent. The following vapour pressures are observed by dissolving X and Y :

$X/mol\; lit^{-1}$ $Y/mm\;of\;Hg$

0.10

0.25

0.01

$P_1$

$P_2$

$P_3$

The correct order of vapour pressure is :

 $(1)\;P_1 < P_2 < P_3$ 

 $(2)\;P_3 < P_2 < P_1$

 $(3)\;P_3 < P_1 < P_2$

 $(4)\;P_2 < P_1 < P_3$

1 Answer
